Technical field
The invention belongs to industrial automations, and in particular to a kind of to be cut by laser the socket combined with laser compound welding
Tube preparation method and device.
Background technology
With the development of the technology of air-conditioning and refrigeration industry and the further stringent control of environmental regulation, heat exchange unit is improved
The coefficient of heat transfer of itself is the overall heat exchange performance for improving heat exchanger, makes up the system caused by alternative refrigerant self reason
The necessary means of the reduction of cold performance.There are problems that refrigeration performance decline based on existing refrigerant and does not develop yet effective
Research object is switched to air-conditioning and the basic element of character-heat exchanger element of refrigeration by Substitute Working Medium, relevant enterprise and scientific research institution, i.e.,
Hollow copper tubing can effectively be solved the above problems by improving the heat exchange property of hollow copper tubing.
The copper pipe of air conditioner refrigerating is mostly the hollow copper core of thin-walled minor diameter, as shown in Figure 1, to provide buffering to refrigerant flowing
Area promotes refrigeration effect, is typically designed the bigger hollow copper tubing region of one section of caliber, and manufacture is in 1301 liang of hollow copper tubing
Side is socketed hollow copper core 1302, hollow copper core 1302 and 1301 clearance fit of hollow copper tubing respectively, to prevent refrigerant from flowing through sky
Heart copper pipe leaks, then hollow copper core 1302 and hollow copper tubing 1301 is carried out socket boxing processing, both ensure that sky in this way
The leakproofness of heart copper pipe 1301, and convenient refrigerant used cycle.
Welding mean common at present has argon arc welding, high frequency induction welding and soldering.Argon arc welding is that one kind relying primarily on electricity
The welding manner of metallurgical reaction occurs for arc heating fusing base material, and weld seam is difficult to be made tiny, and welding heat affected zone is larger so that its
The socket hollow copper tubing of large scale, wall thickness more than 1mm is generally used for weld, and it is hollow to be not suitable for tiny, thin-walled the socket of welding
Copper pipe;High frequency induction welding is the main method of welding socket hollow copper tubing, but since gap when different tube diameters copper pipe is socketed is matched
Property is closed, the kelvin effect both in its welding process is asynchronous with approach effect so that the base material of local melting is easy logical
It crosses gap and flows into inside copper pipe and form that weldering is stifled, and surface contaminants cleaning is not also easy to totally cause weld porosity, easy during military service
Leakage and problem of Cracking occurs, while the technological parameter welded is difficult to set up, significantly limit production efficiency and quality;For pricker
, then it is poor to there is welding joint mechanical property, it is difficult to which the deficiency for ensureing leakproofness directly affects the repetition of welding quality in weldering
Property, the problems such as crackle easily occurs during being on active service, leaks.
Laser welding is a kind of high-quality welding technology quickly grown in recent years, and hot spot is tiny so that weld seam
It is extremely narrow, welding heat affected zone is minimum, become many high-accuracy, high-quality welding preferred techniques.But for the overlap joint of socket pipe
For weldering, since its welding structure itself requires enough soldering areas to ensure telescopic lap splice integral strength mechanical property, singly
Road laser welding cannot be satisfied requirement, need multiple tracks built-up welding, this makes, and technique is cumbersome, cost increases, and limits laser welding and exists
The application in this field.

There are two opposite supporting vertical plates for upper setting, and the top of the supporting vertical plate, which is provided with, is used to support the recessed of hollow copper core 1302
Slot.
The extruding wheel assembly 11 includes two extruding wheels, 1101, two L-shaped adapters 1102, pneumatic clamper 1103, pneumatic clamper turn
Fitting 1104, rod failure cylinder 1105 and bearing 1006.Bearing 1006 is mounted on workbench 1, and rod failure cylinder 1105 is fixedly mounted
On bearing 1006, pneumatic clamper 1103 is fixedly mounted on by pneumatic clamper adapter 1104 on rod failure cylinder 1105, two L-shaped adapters
1102 are separately mounted on two pneumatic clamper arms of pneumatic clamper 1103, and a pair of two extruding wheels 1101 being correspondingly arranged up and down pass through respectively
Screw-thread fit is mounted on two L-shaped adapters 1102.Rod failure cylinder 1105 can drive two extruding wheels or so synchronizing moving, gas
Pawl 1103 can drive two extruding wheels to be located remotely from each other or close.
The course of work of the high-frequency induction laserHybrid welding connection device of above-mentioned socket hollow copper tubing is:
Rotate X-direction mobile mechanism in take-off assembly 4, Y-direction mobile mechanism, 180 ° of rotating mechanisms with guide rail cylinder
Pneumatic-finger 412 is moved to the position (feeding station) at 1301 place of hollow copper tubing between two elastic interstage sleeves by 407 cooperations,
And hollow copper tubing 1301 is gripped using pneumatic-finger 412, then moved to 1302 position of hollow copper core, make hollow copper core
1302 one end is inserted into hollow copper tubing 1301, and feeding action is completed.Later, the pneumatic clamper finger 205 for clamping rotary components 2 clamps
Hollow copper tubing 1301, pneumatic-finger 412 unclamp;Output welding laser beam, focuses on hollow copper core 1302 and hollow copper tubing 1301
The pipe pendant positions (leaning on copper pipe side) of section are socketed, spot welding is fixed, is used for preliminary fixation hollow copper core 1302 and hollow copper
The relative position of pipe 1301;Then, according to the length requirement of workpiece, start laser cutting head and drive cylinder 602, cut using laser
It cuts first 605 output cutting laser beam and cuts off hollow copper core 1302, and keep balance on copper core support element 1004;Output weldering again
Laser beam is connect, rotary components 2 is clamped and hollow copper tubing 112 is driven at the uniform velocity to be rotated together with hollow copper tubing 1301 so that focus laser
Beam is socketed one circle of pipe pendant positions scanning of section along hollow copper core 1302 and hollow copper tubing 1301, to obtain hollow copper core
1302 are socketed the pipe side laser girth joint of section with hollow copper tubing 1301.
Then, high-frequency induction heating coil 504 is powered, and hollow copper tubing 112 and sky are driven by clamping rotary components 2
Heart copper core 1302 at the uniform velocity rotates so that hollow copper core 1302 is socketed section preheating uniformly with hollow copper tubing 1301;When preheating temperature reaches
To after setting value, skin layer fusing occurs under the action of high-frequency current for socket section high-frequency induction heating region, at this time rapidly
Control squeezes two extruding wheels 1101 in wheel assembly 11 and mutually squeezes high-frequency induction heating region, due to being socketed the pipe side of section
It is closed by preamble laser girth joint, fusing metal will be extruded from the core side of socket section (leaning on copper core side), to realize
The solid phase for being socketed section weld metal is coupled.
After 1301 side of hollow copper tubing is welded, pneumatic clamper finger 205 is unclamped, clamps pneumatic-finger 412, control rotation
Cylinder 410 drives hollow copper tubing 1301 to rotate 180 °, carries out the welding of the other side, waits for that 1301 both sides of hollow copper tubing are welded and finish
Afterwards, rotation take-off assembly 4 is stepped back, and two extruding wheels 1101 for squeezing wheel assembly 11 are unclamped and stepped back, and pneumatic clamper finger 205 unclamps,
Hollow copper tubing 1301 is automatically fallen into hopper 12.
The present invention can be changed apparent to one skilled in the art for various ways, and such change is not considered as
It departs from the scope of the present invention.The technical staff in the field is obviously changed as all, is included within this right
Within the scope of it is required that.
